The promotion and consumption of indigenous vegetables could help mitigate food insecurity and alleviate malnutrition in developing countries. In this respect, 17 accessions (candidate breeding lines that have not yet officially been released) of five African indigenous vegetables: amaranth (Amaranthus cruentus), nightshade (Solanum scabrum), African eggplant (Solanum aethiopicum), jute mallow (Corchorus olitorius) and okra (Abelmoschus callei), previously selected for their superior agronomic and horticultural traits, were evaluated in Cameroon for minerals (Ca, Mg, K, P, Zn and Fe), proteins, and carotenoids content. Nutrient content differed significantly (P<0.001) between cultivars. Amaranth (especially line AM-NKgn) had the highest Ca, Mg, and Zn content in comparison to other genotypes studied. Nightshade had the highest K and Fe content. The highest K and Fe levels were found in nightshades BG24 and SS52, respectively. Nightshade had the highest level of protein, especially line BFS1. The highest amount of carotenoids was identified in the eggplant variety Oforiwa. The study revealed that these vegetables are important sources of some vital nutrients. Increased production and consumption of these nutrient-rich vegetables will help reduce the nutrition-related disorders in Africa.
